Piston Seals

The primary function of a piston seal or piston ring is to reliably seal the piston against the cylinder bore while ensuring its efficient movement with minimal friction and without drift . They are used in cylinders to ensure that pressurized fluid does not leak across the cylinder head as the system pressure pushes the piston down the cylinder bore .

K17

K17 double-acting piston seal is a robust five part assembly is designed specifically for one piece pistons in a wide range of medium duty applications . The seal is also suitable for two piece pistons . Comprised of a nitrile rubber sealing element , two split support rings , and two split L-shaped bearings located either side of the seal , the nitrile rubber sealing element is designed to be extremely wear resistant with multi-lips for efficient dynamic sealing with minimal low pressure friction and, when pressurized, will be protected from extrusion damage by the extending lips of the support rings .
